Manny Pacquiao walked off into retirement - and a future as a politician - after winning the WBO International Welterweight championship in his farewell fight with Timothy Bradley.

His 21-year professional career may not, however, be over after the Filipino star left the door open for a return to the ring.

Already a congressman in his native Philippines, Pacquiao is running for Senate in next month's elections.

If successful that is likely to rule out any possibility of the 37-year-old continuing to box, but he showed in the MGM Grand arena in Las Vegas that he still has the power and skill to compete at the highest level.

When asked if his decision to retire was final Pacquiao replied: "Let me enjoy first a retired life.

"If you ask me to come back I don't know, I may be enjoying retired life.

"I'm not there yet so I just don't know. As of now I am retired. I am going to go home and think about it, but I want to be with my family. I want to serve the people."

Despite it being his final fight, Pacquiao showed no signs of slowing down as he secured a unanimous points decision, with all three judges scoring the fight 116-110 in favour of Pac man

He won 10 of the 12 rounds in the contest and he still resembles the fighter who thrilled so many with his romp to titles in eight different weight classes.

He had previously fought Bradley twice for the WBO welterweight title, with one win each in the previous contests, the most recent being for Pacquiao four years ago.
